CIRGULATING-PUMP MECHANISM FOR EXERTING- PRESSURE.

Specification of Letters Patent.

Patented Apr. 21, 1914.

Application filed January 30, 1913. Serial No. 745,255,

To all whom it may concern Be it known that I, EDWARD GUn v'rHER, a citizen of the United States, reslding at West New York, in the county of Hudsonand State of New Jersey, have invented new and useful. Improvements in Circulating- Pump Mechanisms for Exerting Pressure, of which the following is a specification.

My present invention relates to mechanism for exerting pressure in which a suitable vane has imparted thereto a predetermined oscillatory movement simultaneously with lateral reciprocation by positive mechanism, to actuate fluid.

It has already been proposed to exert a pressure upon fluid by a vane disposed within a conduit, this vane receiving its motion in such a manner as to not have imparted thereto movement in a predetermined path, and hence, is actuated for successful opera tion by non-positive or force-closed mechanisms.

The principal object of my invention is to provide a machine of the character described wherein parts move at a positive velocity ratio and hence, fluid may be forwarded thereby in a uniform manner.

Further objects of my invention are, to provide means whereby fluid may pass through the conduit or machine, when inactive, without encountering an obstruction which will resist movement thereof to any material degree; and, to provide a machine which is reversible by actuating the parts in the counter direction to that in which they previously moved.

Other objects of the invention will appear in the following detailed description, taken in connection with the accompanying drawings, and in which drawings: Figure l is an elevation of the machine embodying my invention. Fig. 2 is a central vertical transverse section through the same, parts being shown in elevation to simplify the view. Fig. 3 is a side elevation of the machine. Fig. 4 is a central vertical longitudinal section through the machine.

In the drawings, where similar characters refer to similar parts, 5 designates a conduit, preferably rectangular in cross section, and in the present instance constituting the easing for a pump. The conduit is provided with a reduced inlet 6 at one end, and a reduced discharge 7 at the opposite end, and in operation is usually placed in a tank of movable wall 13 still water, but it may receive its supply in any desired manner.

pen to conduit 5 is a chamber 8, as through way 9 provided in a detachable partition or wall 10 of the conduit, and movable in the conduit is a flat vane 11, adapted to extend from removable wall 12 to rethereof and facing the wall 10.

Positive mechanism, designated generally by 14 is provided for simultaneously imparting an oscillatory movement to the vane about a reciprocable axis intermediate the ends of the latter, whereby the vane in one phase of movement passes through two suction and two pressure exerting strokes. The means providing that reciprocation of the axis of oscillation of the vane be in a predetermined path, may consist in parallel guide-ways l5 laterally at both sides of the vane formed or provided by spacing of the sections of the walls 12 and 13, and roller bearings 16 carried by the vane working in these guide-ways and coaxial with the said axis of oscillation.

As clearly shown in Fig. 4 of the drawing, the portion of the conduit 5 may be milled relatively larger than the width of the vane 11 by feeding the tool from the side of the conduit afterward closed by the partition or wall 10. A substantially liquid tight confinement of the vane laterally of the conduit may then be provided by the insertion of the detachable walls 12 and 13, made in sect-ions to allow for guide-ways l5 and said walls 12 and 13 are then held in place by the provision of wall 10 and their engagement with the vane 11.

The mechanism 14 for oscillating the vane and reciprocating it as described, may comprise a drive shaft 17 extending into chamber 8, as through gland 18; a crank disk 19 having a pin 20; and a rod 21 connecting pin 20 and vane 11, and extending through way 9 hereinbefore referred to.

he operation of the machine is as fol lows: Assuming that the shaft 17 is being rotated so that the disk 19 moves in the direction indicated by an arrow in Fig. 41- of the drawings, this figure shows the vane 11 partially moved in its pressure exerting stroke. That is, to force fluid. confined between the vane, the bottom wall of the conduit and the walls 12 and 13 thereof. As soon as the crank pin 20 reaches its lowermost position, and starts to ascend at the other side of the axis of disk 19, the vane 11 moves in its suction stroke as is obvious from an inspection of the drawings and taking into consideration that the end portion of the vane shown uppermost in Fig. 4 will be lowermost and the other end portion of the vane will start to ascend. By considering the action of this vane during each phase of the movement of disk 19, it will be seen that the vane has imparted thereto two suction and two pressure exerting strokes.

Inasmuch as the vane is positively oscillated about the axis of roller bearings 16, and such axis is limited to lateral reciprocation in a predetermined path, the vane receives its motion through positive mechanism and is not dependent upon the friction of the fluid, in any manner, for successful operation, The wall 10 is provided to confine the fluid to a path of movement longitudinally of the conduit 5. It is also to be noted that when the crank pin is in its uppermost position, the flat vane 11 lies in parallel relation and in close proximity to the wall 10 so that fluid may be conveyed through the conduit from the reduced inlet to the reduced discharge without material resistance to its flow.

An inspection of the drawings will also make obvious the fact that the machine is subject to reversal by moving the elements in a counter direction to that in which they previously moved.

Changes in details may be made without departing from the spirit or scope of my invention; but,

I claim 1. In a machine fOr exerting pressure, the combination of a conduit having an elongated way for the flow of fluid and a reduced ntake and discharge, a flat vane in said conduit adapted to forward the fluid, and means for retaining said flat vane closely adjacent one wall of said conduit and 4' out of alinement with the said intake and discharge for permitting free passage of fluid through the conduit when desired.

2. In a machine for exerting pressure, the combination of a conduit and a vane therein, said conduit being relatively wider than said vane and normally open at one face, detach- 'able walls interposed between the sides of said vane and walls of said conduit, each detachable wall being in sections to provide transverse guide ways laterally of the vane, a detachable cover for the open face of said conduit and engaging said detachable walls to hold the latter in place, means carried by said vane and guided by said ways for confining said vane to a predetermined path transversely of said conduit, and means for simultaneously oscillating and reciprocating said vane in said conduit, substantially as and for the purpose set forth.

3. In a machine for exerting pressure, the combination of a conduit and a vane therein, said conduit being relatively wider than said vane, detachable walls interposed between the sides of'said vane and the walls of said conduit, each detachable wall being in sections to provide transverse guide ways laterally of the vane, means carried by said vane and guided b Y the said ways for confining said vane to a predetermined path transversely of said conduit, and means for simultaneously oscillating and reciprocating said vane in said conduit, substantially as and for the purpose set forth.
